SECONDARY-BATTERY POROUS-MEMBRANE SLURRY, SECONDARY-BATTERY POROUS MEMBRANE, SECONDARY-BATTERY ELECTRODE, SECONDARY-BATTERY SEPARATOR, SECONDARY BATTERY, AND METHOD FOR MANUFACTURING SECONDARY-BATTERY POROUS MEMBRANE

摘要

[Problem] To provide a high-strength, highly uniform secondary-battery porous membrane that is capable of improving the cycle characteristics of a resulting secondary battery and is manufactured using a secondary-battery porous-membrane slurry that exhibits excellent coating performance and contains highly-dispersed nonconductive particles. Also, to provide a secondary-battery electrode and secondary-battery separator having good shutdown functionality. [Solution] This secondary-battery porous-membrane slurry is characterized by containing organic-polymer-containing nonconductive particles, a binder, and a solvent, and is further characterized in that said binder contains particles (A) of an acrylic polymer that has a sulfonic acid group and particles (B) of an acrylic polymer that has an epoxy group.
